I know couple of European country did use that old format and it is no longer legal.
If my memory serve right the red was netrual while green was live { warning : this is a very old colour code }
however you will have to reconfreaged the connection at the motour.
use the bleu for netrual and green for earth connection on the motor and grab a brown tape or sleeve and remarked the red conductor as live conductor.
Otherwise the best legit way is replace the whole cable set to correct colour code.
